high thermal conductivity of sparkplasma process

Custom Technical Ceramics of high quality for industry

Spark plasma sintering (SPS) Innovative sintering process based on a modified hot pressing setup in which an electric current runs directly through the pressing mould (typically graphite) and the component. By means of the pulsed electric current and the “spark plasma effect”, very rapid heating times and short process cycles are achieved.
